Incomplete Dominance makeup worksheet

Front

What is incomplete dominance?

Back

A type of inheritance pattern where the phenotype of a heterozygote is intermediate between the phenotypes of the two homozygotes.

Front

What is the inheritance pattern where both traits are fully expressed?

Back

Co-dominance.

Front

If a tall plant (TT) is crossed with a medium plant (TS), what fraction of the offspring will be tall?

Back

50%.

Front

What happens to the traits in incomplete dominance?

Back

The traits blend together.

Front

What are the genotypes for red, white, and speckled carnations in codominance?

Back

Red = RR, white = WW, speckled = RW.

Front

What is the phenotype of a plant with genotype TS in incomplete dominance?

Back

Medium size.

Front

In incomplete dominance, what is the expected phenotype ratio of a cross between two heterozygotes (TS x TS)?

Back

1 tall : 2 medium : 1 short.

Front

What is the difference between incomplete dominance and complete dominance?

Back

In complete dominance, one allele completely masks the other, while in incomplete dominance, both traits blend.

Front

What is an example of incomplete dominance in animals?

Back

A cross between a red and white flower resulting in pink flowers.

Front

What is the genotype of a medium-sized plant in incomplete dominance if tall is represented by T and short by t?

Back

Tt.
